Yay! I'm so happy you liked it. *whew* I must admit that I was nervous as I wrote the story, hoping that it would match up to the wonderful artwork that you gave me last year.
I'm not a big fan of hero!Harry saving the day, and I wanted to use Snape's intellect, so I thought having him as an Unspeakable with Flitwick one as well (really, who's going to suspect the lovable Charms professor?) woul work quite nicely.
